Abstract
The design of these antennas is in line with the specifications for the futuristic 5G and beyond technologies. The antenna type used for this design is a microstrip patch array antenna with four radiating elements at resonating frequencies of 24GHz, 26GHz, and 28GHz respectively. At these high frequencies, the substrate used is FR4_epoxy, a ceramic material that aids in minimizing mutual coupling effects and has a dielectric constant of Er = 4.4. The resonating frequencies enable the antennas to operate on the millimeter wave band with an enhancement to the throughput, multiplexing abilities, and bandwidth of the antenna. The results obtained at these frequencies peaked at an antenna gain of about 8dB, 3GHz bandwidth, and a return loss of -30dB. These results were then compared to those of earlier works for which microstrip patch antennas were designed.
